Very ancient, very replenished D76d, made up on the 3rd May 1985 and kept going ever since - But kept going carefully with test patches at zone VIII and XI to make sure everything is going well every week or so
I use the alternative replenishment method whereby a fair bit of fresh D76d is used with the D76d replenisher - 70ml of replenisher to 80 inches square each (a sheet of 10x8", 4/5x4 or 1/120 or 1/36-35mm) of mix instead of just the 28ml of D76dR - (See "76 Years of D76, Ryuji Suzuki, Silvergrain.org)
I use a narrow measuring cylinder with a piece of tape glued to it with the number of films to be replenished marked up the tape, for three sheets I top up the the third line and so on
Recently I bought a step wedge via APUG to calibrate a densitometer I had been given - This gives me much greater information on the state of the developer, a crucial thing when using old replenished dev' - Replenished dev' has to do a lot of work it to keep it young and healthy, like all us

My go to developer in the past has been Ilford LC29 but after using Caffenol CL with a semi-stand process that will be my first choice for anything going forward other than if I need something in a hurry, as the 65 minute dev time is the only downside so far (apart from the smell).
Started with D-76, moved to XTol replenished. I didn't see a big difference in negative quality between these two, both were just fine, the ease of replenishment was the biggie for me. Truly, replenished systems are really sweet to use.
I switched to DD-X because my processing volume had changed and to be honest just wanted to try something different. DD-X truly seems to be a bit of a step up in quality from the above, this is highly subjective but it seems to give me negatives that print the way I like easier.
The WD2D+ has been a big surprise. I tried it on a whim here lately just to see why some people like Pyro developers so much. The prints are beautiful so far and films that I found finicky before (in reliably getting the planned contrast from development), like Delta 100, have at least so far been automatic for me in WD2D+ using the numbers right off the instruction sheet.
The finickyness of Delta 100, and the very few roll of TMax 100 that I've tried, has been true for me with D-76, XTol, and DD-X.
WD2D+ does take just a little extra work, a pre-wet step plus measuring and mixing for every run. It requires use within 3-minutes so there's no mixing enough for the day, you have to mix as you go for each tank or tray, and you should use protective gloves.
Even with the extra work I can see the distinct possibility of WD2D+ becoming my general purpose developer if it remains as automatic and reliable as it has been so far. Reliably good results without a lot of thought is really what I want from a general purpose developer.
